As illustrated in FIGS. 2A-2B, the flap 105 according to one embodiment of the present disclosure has a first end 135 hingedly connected to the walls along which the flap 105 is provided and a second, free end 136 opposite the first end 135. For instance, in the illustrated embodiment, the first end 135 of the flap 105 is hingedly connected to the ends walls 122, 123 and one of the sidewalls 118, 119 of the lower portion 102 of the flexible storage container 100. Accordingly, the flap 105 is configured to move between an open position (see FIG. 2A) in which the zipper 103 is exposed and a closed position (see FIG. 2B showing a partially closed configuration) in which the zipper 103 is concealed or covered by the flap 105. Additionally, in the illustrated embodiment, the first end 135 of the flap 105, which is hingedly connected to one or more of the walls 118, 119, 122, 123 of the lower portion 102, is above the zipper 103 (e.g., the first end 135 of the flap 105 is between the zipper 103 and the upper wall 107 of the upper portion 101) and the second end 136 of the flap 105, when the flap 105 is in the closed configuration, is above the zipper 103 (e.g., the second end 136 of the flap 105 in the closed configuration is between the zipper 103 and the base wall 117 of the lower portion 102).

Furthermore, in the illustrated embodiment, the flexible storage container 100 includes one or more fasteners or other mechanisms or devices for detachably securing the flap 105 in the closed configuration. In the illustrated embodiment, the flexible storage container 100 includes hook or loop-type fasteners 137 on outer surfaces 138 of the walls 118, 119, 122, 123 along which the zipper 103 extends (e.g., hook or loop-type fasteners 137 on outer surfaces 138 of the end walls 122, 123 and one of the sidewalls 118, 119 of the lower portion 102). In the illustrated embodiment, the hook or loop-type fasteners 137 are located below the zipper 103 (e.g., the hook or loop-type fasteners 137 provided on the walls 118, 119, 122, 123 along which the zipper 103 extends are between the zipper 103 and the base wall 117 of the lower portion 102). Additionally, in the illustrated embodiment, corresponding loop or hook-type fasteners 139 are provided on an inner surface 140 of the second end 136 of the flap 105. When the flap 105 is in the closed position, the loop or hook-type fasteners 139 on the flap 105 are engaged with the corresponding hook or loop-type fasteners 137 on the walls 118, 119, 122, 123 of the lower portion 102, which detachably secures the flap 105 in the closed configuration. Because the first end 135 of the flap 105 and the hook or loop-type fasteners 137, 139 are provided on opposite sides of the zipper 103 (e.g., the first end 135 of the flap 105 is connected to one or more of the walls 118, 119, 122, 123 above the zipper 103 and the hook or loop-type fasteners 137, 139 on the one or more walls 118, 119, 122, 123 are provided below the zipper 103), the flap 105 extends over the zipper 103 when the flap 105 is in the closed configuration. In one or more embodiments, the first end 135 of the flap 105 may be hingedly connected below the zipper 103 and the hook or loop-type fasteners 137 may be located above the zipper 103. In one or more embodiments, the flap 105 may be detachably secured in the closed configuration by any other suitable fastener or fastening mechanism. For instance, in one or more embodiments, the inner surface 140 of the second end 136 of the flap 105 may include a series of minute protuberances that are configured to adhere to the outer surfaces 138 of the walls 118, 119, 122, 123 via the Van der Waals force. In one or more embodiments, the flap 105 may be detachably secured in the closed configuration by clasps, button snaps, hooks, or combinations thereof.
